One reason Internet memes — the quirky photos with societal observations that are passed along like genes or around like germs — work so well, is that they tap into something of the moment, a fleeting notion that captures the here and now.

A visual meme is more like a snapshot than an "iconic image" — such as V-J Day in Times Square -- says NPR photo editor Claire O'Neill. An iconic photo is timeless. But "what's 'timeless' about memes is not so much the image, or joke itself, but the timeless thing it is revealing about people."

Visual memes "are a form of observational humor," Claire says: "Everyone knows what it feels like to feel this way."

A meme will probably not live forever, Claire says, but that "sense of feeling bewildered will."

So when we found — in casual research — decades-old images in the archives of the Library of Congress that remind us of memes today, we couldn't help but wonder what kind of smart or snarky memes they would have inspired in their times. Any suggestions? Please keep it civil.
